This study was designed to better understand the relations between learning disabilities and different levels of latent cognitive abilities, including general intelligence (g), broad cognitive abilities, and specific abilities based on the Cattell-Horn-Carroll theory of intelligence (CHC theory). Data from the "Differential Ability…

This article presents critical issues related to word reading development within Ehri's theoretical context by focusing primarily on the relation of decoding skill (of nonwords) to word reading and the development of unitization. Within this context, issues and considerations related to research, measurement, and reading development are presented…

In response to a previous article, the paper suggests it is unrealistic to expect one theory or even multiple theories within one paradigm to explain learning disabilities. The emphasis on reaching a consensus regarding theory or paradigm is seen as unproductive. (DB)

The article deals with the problem of scientific definitions, focusing on its application to learning disabilities. (DLS)

In response to a previous article, the paper discusses the distinction between basic and applied research, two contributions of applied research to theory concerning learning disabilities, and issues in metatheory development. (DB)

In response to a previous article, the paper suggests that solutions to current problems in learning disabilities are not directly dependent upon, and may not be affected by, basic research. The necessity of a coordinated theoretical foundation for research and the wisdom and feasibility of a movement to basic research are discussed. (DB)

In response to a previous article, the paper notes additional reasons for the deficit in basic research and theory in learning disabilities, stresses the need for more good systematic research using multiple methods, and suggests that a metatheory for learning disabilities is not yet possible or profitable. (DB)

In response to a previous article, the paper stresses that, in addition to theory development, the field of learning disabilities needs to resolve definitional issues involving disability specificity, intelligence, measurement concepts, and the continua of abilities. Suggestions for developing operational definitions of both learning disabilities…

In response to a previous article, the paper argues that effective instruction of the learning disabled is most likely to develop from systematic theoretically based research though instructional studies can contribute to theory development. Research in many other areas is necessary to develop the powerful teaching methods required. (DB)

In response to a previous article, the paper finds weaknesses in the mechanistic worldview represented by the emphasis on information processing research in constructing a metatheory for learning disabilities. An alternative--contextualist--world view is proposed which is holistic, social, and developmental providing insight into processes of…

In response to articles concerning the author's earlier paper, the paper responds to criticisms concerning contextualism, the role of metatheory, distinctions between basic and applied research, cognitive components and specificity, the science of learning disabilities, neurological indices, model validation, and the nature of learning…

A review and analysis of current research on subtypes of learning-disabled children argues against a "single syndrome" theory of learning disability and demonstrates the feasibility of creating more homogeneous diagnostic groups within this broad and ill-defined category of exceptional children. (Author/CL)

Learning disabilities is presented as a construct supported by psychoeducational, socioemotional, and physiological data, as illustrated by the M. Meeker paradigm. (Author)

The author reviews Plato's epistemological speculations on the nature of perception, memory, and ideation and suggests that, although this dialog is primarily concerned with the nature of knowledge, it can also be construed as reflecting a Platonic conception of cognitive disabilities. (Author)

The authors assert that progress in conceptualizing learning disabilities and related intervention procedures is dependent on systematic, consistent, and educationally grounded theory, and that each practitioner should adopt a system and use it consistently. A cognitive-field model is illustrated and its use as a foundation for educating LD…
